CLOSURE DEVICE.

Application filed March 28, 1922.

7 '0 all whom it may concern:

Be it known that I, LOUIS R. ONEILL, a citizen of the United States,residing at No. 835 Clinton Avenue, in the city of Newark,

county of Essex, State of New Jersey, have invented a new and usefulImprovement in a Closure Device.

One important object of the invention is to provide a device that willbe securely 10 connected with the container not only when in a positionto close the discharge orifice, but also when removed therefrom, so thatit can not become detached and lost. In this connection it may bepointed out that the positively connected character of the device isprotection against its acquiring dust, dirt and germs, as a result ofaccidentally falling or being placed in unsanitary surroundings.

Another advantage which is obtained in the use of a ositively connectedclosure device of this c aracter is that the contents of the containerare protected against the detrimental effect of continued exposure tothe atmosphere due to loss or misplacement of the closure device. Thisadvantage is particularly marked in the case of ,containers with liquidsor other substances which quickly volatilize or evaporate when exposedto air.

. Likewise, it may be pointed out that the device may be readily appliedto the conventionally made tube without involving any change in itsmethod of manufacture.

The device is of comparatively simple construction. Brieflydescribed itconsists of a cylindrical collar or sleeve with a smooth inner side,designed to slide along a smooth exterior wall of a discharge nozzle,

on the lower part of which sleeve are mounted two diametrically oppositeverti cal arms supporting a cup-shaped top with a screw threaded innerwall, designed to revolve about an upper exterior threaded part of thedischarge nozzle. As the cap is rotated about the nozzleof thecontainer, so as to move upward, the closure rlevice is raised and maybe swung on the pivots away from the orifice of the tube. 'In clos- 5.ing the orifice, the cap is swung back to the vertical and is rotateddownwardly.

For a fuller understanding of the invention, reference is to be had tothe following description and accompanying drawings.

Serial No. 547,583.

Fig. 1 is a side elevation with the closure in a closed position, andFig. 2 is a longitudinal sectional view partly in elevation taken atright angles to Fig. 1.

Referring in detail to Figs. 1 and 2, the letter A designates a tube orcontainer of conventional construction provided with a cylindricaldischarge nozzle, a, which is exteriorly threaded at its upper part, buthas a smooth lower part and is formed with a discharge orifice, b. Acylindrical sleeve, 15, is designated to frictionally slide along thesmooth surface of b, on the lower part of which sleeve are situated twotrunnions, diametrically opposite and designated 4 and 5.

The closure element, B, consists of a circular dish, 6, with acylindrical rim, 7, reseinhiing a cup with two ears, 8 and 9, extendingdownward and substantially at right angles to 6, which are pivotallyconnected with the sleeve, 15, by means of trunnions, 4 and 5, which maybe either placed in the sleeve, 15, or afiixed to the ears, 8 and 9, asshown in Fig. 2, in which case they would engage in the sleeve, as

engage and shown at 16, and thus secure the closure The device isoperated by grasping the closure member when it is in a closed position,at the, top between the thumb and forefinger and by turning same untilthe screw threaded portion of the cap is raised free of the screwthreaded part of the nozzle. The closure element may then be raised to asufficient height above the top of the nozzle to permit it to be swungto either side thereof. The closure member, B, is then swung to eitherside of the nozzle away from the orifice to allow the free discharge ofvthe contents of the container. It may be observed that as the cap israised upwardly, it is prevented from becoming separated from the nozzleas the lower band comes in contact with the threaded part of the nozzle,

To replace the closure member in a closed position, it is swung to thevertical position over the container and the cap is screwed downwarduntil the top of the closure member rests snugly against the dischargenoz-,

zle, at

The substance out of which the device may be constructed may be anymaterial that can be advantageously utilized for the purpose ofproviding a closure device of the within description, sheet metal beingprefer able because of its practical'utility and inexpensiveness.

Having thus described my invention, what I now claim and seek to protectis as follows:

A container closure, comprising a discharge nozzle having a smoothcylindrical portionand an exteriorly threaded portion of a greaterdiameter than the threaded portion, said smooth portion beingsubstantially longer than the threaded portion, a sleeve mounted on thenozzle, and provided with a pair of oppositely disposed openings, and aninteriorly threaded closure cap having a pair of downwardly extendingand converging arms formed integral with the cap and adapted for pivotalconnection with the sleeve, said sleeve being of a width that willpermit the cap to clear said discharge nozzle when swung to and from itsclosed position.
